Family/Group: Flora
Taxonomic Class: S (Assumed)
Published: MPB 38, pending
NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

This was a one-night target of opportunity, i.e., in the same field as a planned target. The period solution is based on a half-period analysis and assumption that, with an amplitude of ~0.3 mag, a bi-modal solution is fairly likely.
